Re: [eclipselink-users] Does not work with classes packaged in a separat

[Shaun Smith <shaun.smith@xxxxxxxxxx>]

Hi Charles,

   You should have no trouble with entities spread across bundles.  I have an example with 3 entities each in their own bundle and a 4th bundle containing the persistence.xml and the code that creates the EntityManagerFactory.  What you didn't mention in your remarks, but I can see from your configuration, is that you are using Spring and Spring's load time weaving support.  EclipseLink's Equinox weaving support prior to version 2.0 does require all entities to be packaged in the same bundle.  Perhaps you can try EclipseLink 2.0 to see if this solves the problem.  However, I suspect the problem is a Spring/EclipseLink in OSGi problem.  Can you post the error you're seeing?

EclipseLink 1.2.0 does not work on Apache Felix 2.0.1 platform when the
entities classes are deployed in another bundle than the one containing the
persistence.xml file.

Remark : They are no conflicts between the two bundles as the packages are
well exported and imported

Here is the spring / persistence config files
